“…The hematological indices are recommended for evaluating the metabolic and immunological status of fish suffering from toxic and pathogenic stressors [ 45 , 46 ]. The levels of hemoglobin (Hb) and red blood cells (RBCs) indicate the anemic and respiration capacity of blood cells, whereas hematocrit (PCV) and white blood cell (WBCs) levels show the immunological status of fish [ 47 ].…”

Waterborne herbicides are stressful agents that threaten the productivity and safety of finfish species. In this study, the toxicity impacts of atrazine (ATZ) and the protective role of fucoidan were investigated on the health performance of Nile tilapia. For 40 days, the total number of 180 Nile tilapia was assigned in four groups (triplicates, 15 fish/replicate), where the first (control) and third groups were offered the control diet, while the second and fourth groups were offered a fucoidan (FCN). Further, in the third and fourth groups, the water was mixed with atrazine (ATZ) at 1.39 mg/L daily. The growth rate, FCR, and survival rate were markedly enhanced by fucoidan but severely declined by ATZ exposure (p < 0.05). The morphological structure of the intestine in the control fish revealed normal structure, while fucoidan-treated groups showed eminent enhancement and branching of the intestinal villi. The intestine of ATZ-treated fish revealed deterioration and the intestinal mucosa, inflammatory cell infiltration, and separation of lining epithelium. The highest Hb, PCV, RBCs, WBCs, total protein, and albumin were observed in Nile tilapia fed fucoidan, but the worst values were seen in ATZ-intoxicated fish (p < 0.05). The liver-related enzymes (ALT and AST) and kidney function (urea and creatinine) showed impaired values by ATZ toxicity and were regulated by dietary fucoidan. Meanwhile, fish fed fucoidan and exposed to ATZ had lower total cholesterol and triglyceride values than fish exposed to ATZ without fucoidan feeding (p < 0.05). The SOD, CAT, GPx, cortisol, and glucose levels were increased in ATZ-exposed fish and reduced by fucoidan (p < 0.05). However, the level of malondialdehyde (MDA) was reduced in fucoidan-fed fish and increased in ATZ-exposed fish (p < 0.05). Altogether, dietary fucoidan is required in fish diets to alleviate the impacts of ATZ-induced toxicity.

“…However, exposure to ATZ result in impaired Hb, PCV, RBCs, and WBCs, probably due to oxidative stress and low metabolic function [ 15 ]. Similarly, chirruh snowtrout ( Schizothorax esocinus ) [ 45 , 48 ] exposed to ATZ had deteriorated hematological traits while fish fed fucoidan had enhanced hematological indices.…”

“…Atrazine (2-chloro-4-ethylamino-6isopropylamino-1, 3, 5 triazine) is the active substance of a plant protection product belonging to the triazine chemical family which has a herbicidal effect. It is widely used in agriculture to control weeds in various crops, such as maize, sorghum, and sugarcane [34,35]. Atrazine is a weak base with the chemical formula C 8 H 14 ClN 5 , a molecular weight of 215.68 g mol −1 , and a low solubility in water (35 mg L −1 at 25 °C) but a high solubility in organic solvents, with a log K OW partition coefficient of 2.61.…”

The rapid growth of anthropogenic activities in recent decades has resulted in the appearance of numerous new chemical compounds in the environment, known as “emerging pollutants” (EPs) or “contaminants of emerging concern” (CECs). Although partially or not yet regulated or monitored, there is growing research interest in these EPs among the scientific community because of their bioaccumulation, persistence, and adverse effects. Among these, endocrine disruptors, pesticides, and pharmaceuticals can have harmful impacts on human health and the ecosystem. Conventional wastewater treatment technologies are not effective in removing these contaminants, allowing them to be released into the receiving environment. In order to improve the understanding of emerging pollutants, this review discusses the source, occurrence, and impacts of bisphenol A, atrazine, amoxicillin, and paracetamol as model molecules of emerging environmental pollutants, an issue that remains underrepresented in Morocco. Then, treatment methods for EPs are reviewed, including adsorption, advanced oxidation processes, biodegradation, and hybrid treatment. It is proposed that adsorption and photocatalysis can be used as simple, effective, and environmentally friendly technologies for their removal. Thus, we summarize some of the adsorbent and photocatalyst materials applied in recent work to control these pollutants. Towards the end of this paper, the development of inexpensive and locally available (Morocco) materials to remove these compounds from wastewater is considered.

The current study was designed to evaluate the comparative effects of three selected chemicals such as emamectin (insecticide), acetochlor (herbicide) and topsin-M (fungicide) on haematology, biochemical profile and histopathology of grass carp (Ctenopharyngdon idella). A total of forty C. Idella was collected from fish farm Hattian Kamra and transported to the Chemistry lab of Government Post Graduate College Haripur in plastic bags containing dissolve oxygen. After acclimatization for a week they were randomly segregated in four groups (E0, E1, E2 and E3) and treated with 5ppb emamectin, acetochlor and topsin-M respectively. After 96hrs of chemical treatment, blood and tissue samples were collected from both control and treated groups for investigation of biochemical and histopathological alterations. Obtained results exhibited significant alteration in haematological parameters i.e. total white blood cells count, MCV, MCH and number of platelets significantly (p<0.05) increased while Red blood cells count, hemoglobin, PCV and MCHC significantly (p<0.05) decreased in the experimental groups E1, E2 and E3 as compared to control group. Significant (p<0.05) changes were observed in biochemical parameters i.e. increase in serum glucose, bilirubin, albumins, blood urea, uric acid, cholesterol, serum calcium, phosphorous, sodium, potassium, serum lipase, CKP, LDH and CK MB, while significant decrease in creatinine, triglycerides, HDL-cholesterol, serum iron, serum amylase, SGPT, alkalinity and Phosphate was observed. The observed Histopathological changes in gills include epithelial
